'Ithis invention relates to improvements in Y register hooks for holding printing plates in position upon a base and for adjusting the same, and one of the objects of the invention is to improve and simplify the construction `of the hook, and at the same time provide a sturdy construction in which the parts may be readily assembled and which hook majT be readily placed in position within a groove. in the base from the upper face of the base. A further object is to provide an improved hook of this character which is provided with improved means for locking or securing the same against accidental removal from the groove in the base, but which will permit a micrometer adjustment of the same, the lockingand securing means being so constructed or shaped that the hook may be readily moved in the groove in one direction' and may be 2o readily removed by raising one end of the hook to causethe locking means to. be rend ered inactive or'shifted. to an inactive position by engagement of the locking means with a portion of the wall of the groove by the tilting or raising movement of one end of the hook. A further object is to reduce the size and width of the hook, thereby rendering it possible to provide al greater number of `grooves vin the base than has heretofore been possible A with the use of other hooks, while at the same time the power and strength of the hook will `not be impaired or reduced.

Erl

A further object is to provide improved locking means for locking the adjusting means againstretrograde movement in the groove and which locking means is adapted vto be rendered inactive by the insertion of the key for adjusting or operating the hok.

A further object is to pnovide an improved construction and arrangement of groove\and rack in the base to provide a settlin space for cleaning liquid and foreign partie es.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists inthe features of novelty in. substantially the con-A j struction, combination and arrangement of the several parts, hereinafter more fully described and claimed and shown in the accom,

vthe principles of this invention.

Figure 14 is a top plan view of a rack similar to the rack shown in Figure 13.

The hook consists essentially of a body portion 15, which -lis rectangular in configuration A and comparatively narrow. Swiveled to the A body portion, and adjacent one 'end thereof, so as to project thereabove, is a plate engaging member or clamp 16 which is preferably considerably wider than the width of the body portion 15, a portion of the member 16 being reduced as at 17 and .rounded so as g5 to iit -within aA socket 18 opening through the top of the body portion. The plate engaging member is held against displacement preferably by means .of jpins or fastemng members 1.9-205Whceensase is e9 @anular 1' l 22, which co-ope'rate with the groove 21.

i flat portion 32 in the ratchet A Worm 23 is arranged uprightly in the socket 18 beneath the plate engaging member, and one end of the Worm rests upon the base 24 of vthe socket. The worm 23 is provided with an opening 25 therein which is angular in cross section, and this opening 25 registers with an opening 26 in the plate engaging member 16, so ,that a toolor implement 27 having its extremity 28 angular in cross section to correspond with the shape of the opening 25 in the Worm 23, may be inserted through the opening 26 and into the opening 25 for rotating the worm 23 with respect to the plate engaging member 16.

The upper extremity of the Worm 23 is reduced as at 29', and one portion of this reduced portion is preferably flattened as at 30 (see Figure 10) so that when a .ratchet wheel 31 is? placed upon the reduced portion 29, a

wheel 31 will cooperate with the flat face 30 of the reduced portion 29, to secure the ratchet Wheel to the Worm 23 forrotation therewith. l

A locking member is provided with a circular recessed extremity' 34 and a depending formation 35 which latter acts as a pawl tol co-operate with the teeth of the ratchet wheel The portion 35 is preferably formed by being struck out of the body portion of the locking member and deflected so as to engage into the teeth of the ratchet.

T he other extremity 36 of the locking member 33 is engaged by a spring 37, the spring being secured to one end of the body portion -15by a' suitable fastening device, such as a j screw 38.

The normal tendency of the spring 37 is to.

move the locking member in a direction that the pawl 35 will engage in the ratchet teeth of the ratchet wheel 31 and the circular end 34 registers with the opening 26 in the plate engaging member 16 and projects partially over the opening 25 in the worm 23 so that when the tool 27 (see Figure 11) is inserted in the opening 26, a portion of the tool will engage the circular end 34 of the locking member 33 and move the latter backwardly so as to cause the pawl or Jformation 35 to move out of engagement with the teeth of the ratchet 31,and against the stress of the spring 37.

rl`his operation is caused at the time that the angular extremity 2 8 of the tool is enteringthe angular shaped recess 25 of the worm 23.

Then the Worm 23 is thus released or unlocked the Worm may be rotated by .the tool. lVhen, however, the tool is not inserted, the spring 3T will move the locking member 33 in a direction to cause the pawl or formation 35 to engage the teeth of the ratchet 31 and thereby lock the Worm 23 against rotation. T his locking movement will hold the entire hook against retrograde movement, but when released the Worm 23 serves .as a means for producing a micrometer adjustment.

(lo-operating with the worm 23 is a Worm gear 39, the teeth of which mesh With 'the worm, and the Lgear 39 is rotatable about a arately and fastened to the body portion.

The stud is of a length -just slightly greater than the tliiclrness'ofV the gear 39 and both will be housed' and stand Within the chamber 40 so 'that one sidev of the gear 39 will be protected by a solid Wall formed by 'a portion Y,

of the body 15.

The gear 41 is held against displacement by means of a screw or bolt 42 which is threaded into the stud, the head 43 of the bolt being of a diameter somewhat greater than the eX- ternal diameter of the stud, thereby serving as a means for preventing the gear 39 from being detached from the stud 41.

The teeth of the gear 39 project beyond the bottom of the body portion 15, through an opening '44 in the bottom of the body 15 whichv communicates with the chamber 40. With this construction it will be manifest that when the worm 23 is rotated the gear 39 Will be correspondingly rotated.

Fastening members 45 are provided for the hook and these fastening members are arranged side by side, adjacent the top of the body portion 15 and -are=mounted by one extremity as at- 46, to the body portion, so that 5 the other ext-remities47 of the locking'members may be projected laterally beyond the sides of the .body 15 and may be compressed or moved together towards each other so that Ythey will not project beyond the sides of the body, for a purpose to` be set forth.

The body portion 15 is provided with recesses 48 opening through the sides thereof adjacent one end and communicating with the extremities ofthe recess 48-are reduced recesses 49-50 also opening through the side faces of the body 15. The reduced recess 49 opens through the end of the body 15 and each of the recesses 49 has communication with recesses 51 opening through the end of the body 15. The recesses 51 are separated by means of a partition 52.

The recesses 49 and 50 are of a Width just slightly greater than the Width of the locking members 45, the ends of which fit Within the respective recesses v49 and 50, While the recess 48 intermediate the recesses 494-50 arevof a widthsomewhat greater than the width of the adj acentl portion of the locking members 45. This provides for space. for dirt accumulations and will tend to keep the catch in service a greater length of time without necessitating cleaning.' f

f Depending from the free extremities of the locking members 45 are projections 53 which project into the recesses 51 and co-operate with the walls of the recesses 51 for limiting the outward movement of the locking members and also serve to limit the inward move ment of these members.

A resilient element 54 preferably in ythe form of a coil spring, is disposed between the locking members 45 and passes through a recess 55 in the body portion 15. The resilient element 54 tends normally to swing the locking members 45 outwardly and away from eachother to cause them to project beyond the` lateral faces`of the body portion 15, but

may be compressed so as to permit the locking members to be pressed inwardly'.

The lower faces of the locking members forth, and the upper faces 57 are rounded as shown more clearly in Figures 1 and 2, for a purpose to be r,setforth.

The catch thus formed is adapted to be seated in a groove 58 in a base plate 59 and thegrooves 58 open through the top of theplate and are shaped to form overhanging flanges 60, see particularly Figure 6.

The grooves are-alsoprovided with lateral projections 61, adajc'ent but spaced above the bottom of the groove'which project inwardly, and theseprojections 61-.serve` as a means for maintaining the hook against lateral displacement within the groove.

.Within the groove is arranged a rack 62 which may be secured in position in any suit-- able mannersuch as by means of fastening screws 63 passing through the bottom of the base and engaging therack.

The rack 62 is of a width considerably less than the width of the groove and the teeth 64 of the yrack are cut considerably deeper than. the height of the teeth ofthe gear 39` y which co-operate with the rack, as shown more clearly in Figures 5 and 6. The teeth of the gear 39 and the teeth 64 of the` rack 62are flat faced, and by providingl theispace between the teeth 64 and all the teeth of the gear 39 pockets will be formed for receivingd-irt accumulation and by arranging the rack 62 in the center of the bottom of the groove a gutter will be formed in the bottom of thefgrooveV on each side o f the rack to accommodate d irt. i

In Figures 13 and -14 there is shown an. other form of rack which embodies, longitudinal side members 65 which supportthe teeth 66 by their extremities so as to form a projected beyond the locking members 45 engaging the side-walls of the `groove will force the locking members inwardly and thereby permit the hook to be Ilowered into lthe groove.

lVhen the hook is thus seated ther spring 55 will then project the locking members 45 to cause them to engage beneath the overhanging flanges 60 of the groove. 'The hook will then be seated in the groove and may be` moved` forwardly and b'ackwardly in the groove by the insertion of the tool 27 into-the opening 26 in theplate engaging member l16. This will unlock the Worm 23 and by rotating the tool either forwardly 'or backwardly the `hook may be advanced or retracted. Immediately upon removing the tool 27 the hook will be locked against retrograde movement. f. A

In order to remove the hook, the operator may engagea tool in a recess 67 formed in the rear end ofthe body 15 and by pryingl .up or raising the rear end of the body portion 15 the hook may be removed from the groove. This will be permittedby reason of the rounded upper portion 57 o'f the locking members 45 engaging the edges of the oif'erhanging portions 60v0f lthe groove 58 in the base; as the rounded portion contacting with the edge of the groove willcause the members45 to be forced inwardly against the stress of the spring 54 during thee raising of the rear end of the hook.

, With this improved construction a very narrow hook may be provided and on the basis of ten grooves to a standard' 24 by 24 pica mounting base, the groove for the hook will occupy only about one-fourth of an inch and the plate support strip will then be approximately five-sixtcenths of an inch wide.

It will also be manifest that with this improved construction there is provided a lock be automatically locked. Furthermore, withthis improved construction the washing fluid and the ink will not clog or obstruct the op,- eration of the `hook as the fluid will find its way down the side walls to the bottoms of the grooves into a settling space.
